possible irq lock inversion dependency detected
Apr 3 10:12:07 moka kernel: [ 10.639975] modprobe/1041 just changed the
state of lock:
Apr 3 10:12:07 moka kernel: [ 10.639977]
(&(&dev_priv->context_switch_lock)->rlock){-.....}, at: [<ffffffffa031e3df>]
nouveau_irq_handler+0x5f/0x130 [nouveau]
Apr 3 10:12:07 moka kernel: [ 10.639993] but this lock took another,
HARDIRQ-unsafe lock in the past:
Apr 3 10:12:07 moka kernel: [ 10.639994]
(&(&dev_priv->ramin_lock)->rlock){+.+...}
Apr 3 10:12:07 moka kernel: [ 10.639997]
Apr 3 10:12:07 moka kernel: [ 10.639997] and interrupts could create inverse
lock ordering between them.
